ポリチオスルフェンアミド官能基を有するカップリング剤を含むタイヤ用ゴム組成物
Document Type and Number:
Japanese Patent JP4391238
Kind Code:
B2
Abstract:
An elastomeric composition usable for the manufacture of tires, based on at least (i) a diene elastomer, (ii) an inorganic filler as reinforcing filler and (iii), as (inorganic filler/diene elastomer) coupling agent, a organosilicon compound which is at least bifunctional and can be grafted on to the elastomer by means of a sulfur group having a polythiosulfenamide function, of formula: ≡Si-A-Sx-NR1R2, (I) in which: A is a divalent bond group, whether straight-chain or branched, which makes it possible to join the polythiosulfenamide group to a silicon atom of the organosilicon compound; x is an integer or fractional number of from 2 to 4; R1 represents hydrogen or a monovalent hydrocarbon group; R2 represents a monovalent hydrocarbon group selected from among C3-C8 alkyls, whether straight-chain or branched, C5-C10 cycloalkyls, C6-C18 aryls and (C6-C18)aryl-(C1-C8)alkyls; R1 and R2 possibly forming together and with the nitrogen atom to which they are bonded a single hydrocarbon ring. Tires and tire treads comprising a composition of this type.
